What is Polymarket?

Polymarket is a decentralized prediction market platform where you trade shares representing outcomes of real-world events. If your prediction is correct, shares pay out $1. If wrong, they're worth $0.

Example: "Will it rain tomorrow?"

YES shares trading at $0.65
NO shares trading at $0.35

If you buy YES at $0.65 and it rains:
- You receive $1.00
- Profit: $0.35 (54% return)

If it doesn't rain:
- Shares worth $0.00
- Loss: $0.65
